In "The Volcano Makers," Dr. Arbon’s desperate act of sabotage ignites a chain of volcanic eruptions across North America, driven by his belief that his colleagues have betrayed him. As Magnus races to stop the escalating disaster, he uncovers a deeper conflict between a man’s fractured trust and the machines he once commanded. Written by Russ Manning and Don R. Christensen, with art by Manning and Royer, and a cover by George Wilson, this 1965 issue delivers a tense, grounded sci-fi thriller where the real fire isn’t in the earth—but in the mind of a broken scientist.
